| Abstract: | The influences of using the anti-welding heating processing method on the stress corrosion resistance and fatigue resistance of 16MnR steel and its mechanism were presented,a heating processing was made of the samples of 16MnR steel separately at 250℃ and 350℃,and cool water was used to quickly cool the weld seams of the samples to make the weld seams obtain lower negative temperature difference than their adjacent zones,the result of regulating and deleting the residual tensile stress of weld was realized. |
